Hello,

I forgot nut since more than a year because a lot of job with other 
application

My server nut failed since severals months

We had 3 electric failure so I must install a new server nut

I work with ubuntu 10.04.4 (64bits) / I installed nut 2.4.3 with deposits

I have a MGE Pulsar evolution 2200 connected on usb

last week when I began my tests all was ok (communication etc etc ..)

Yesterday, I tried a simulate electric failure and now, my ups is not 
recognized on usb

the lsusb command doesn't find anymore my ups
when i unplug/plug it i have these errors**

onduleur kernel: [  279.070014] usb 4-1: new low speed USB device using 
uhci_hcd and address 7

**I had this last year on my old server but i never found how to resolve

When nut service start i normally have this in syslog

Can't connect to UPS [OND1] (usbhid-ups-OND1): No such file or directory

What can I do ?

  Thanks a lot for your help
